FYXnav-B High-Integrity Precision GPS with Barometer

Calculated at Checkout

Out of stock

FYXnav-B is a high-integrity GPS navigation source with an integrated barometer.  The FYXnav-B GPS combines a high precision WAAS GNSS sensor with an integrated RAIM processor for resilience against jamming, spoofing, and GPS range errors.   FYXnav-B provides reliable navigation in challenging environments and the integrated high-resolution barometer provides pressure altitude information for use with the Ping ADS-B family.

The Ping mobile application for iOS and Android allows pilots to program their aircraft ICAO, callsign and aircraft type for broadcast over ADS-B.

Key Features:

  • Performs in low sensitivity or high GPS multipath areas.
  • Supports GPS/SBAS GNSS constellations.
  • Battery backup option for fast TTFF.
  • UTC timing output for UAT ADS-B medium synchronization.
  • Integrated RAIM processor for security and integrity protection.
  • Advanced jamming and spoofing detection.
  • Uses SBAS corrections and health messages to detect and correct satellite range errors.
  • Satellite pseudo-range step errors detected and excluded.
  • SBAS fast and long term corrections applied.
  • High-resolution barometer for pressure altitude encoding.
